[tlug] Weird Mail Question

["lists" <lists@example.com>]

Hello,

 

I got the following mail from User A, sent to a mailing list: staff@example.com .

It contained a 1.23Mb file attachment called Virex_Demo.sit  , which caused it to be rejected and bounce with a "Message too long" message.

 

When I look at the main headers, it looks like another user has sent the mail, setting the sender to owner-staff@example.com .

 

Any thoughts on this?

 

Bounce message and headers follow.

 

Thanks,

 

Shawn
